Abstract

LA INVENCION SE REFIERE A UN SISTEMA Y UN DISPOSITIVO PARA ENCENDER COMBUSTIBLE SUMINISTRADO AL INTERIOR DE UN HORNO COMO PARTICULAS (1) SOLIDAS O FLUIDAS, Y QUE CONSISTE EN, POR EJEMPLO, LICORES GASTADOS DE LA INDUSTRIA DE LA PULPA Y EL CONTENIDO ORGANICO DE LOS CUALES SE QUEMA PARCIALMENTE COMO HULLA RESIDUAL DE LA INDUSTRIA (2) SOBRE EL SUELO (3) DEL HORNO, CON SURTIDORES(4) DE GAS CONTENIENDO OXIGENO, QUE USUALMENTE ESTAN SITUADOS EN FILAS HORIZONTALES Y PARCIALMENTE POR ENCIMA DEL HORNO COMO HULLA RESIDUAL EN PARTICULAS SUSPENDIDAS, Y COMO VOLATILES, UTILIZANDO FILAS VERTICALES DE SURTIDORES (5) DE GAS CONTENIENDO OXIGENO, QUE ORIGINAN FUERTES FLUJOS PERPENDICULARES A LAS FILAS DE LOS SURTIDORES, O, EN OTROS TERMINOS, PROPORCIONAN UNA BUENA MEZCLA HORIZONTAL, FACILITANDO LA QUEMA CON CONTENIDO DE OXIGENO INFERIOR, REDUCIENDO ASI LAS EMISIONES DE NOX, PERO, POR OTRA PARTE, FLUYE GAS VERTICAL ESCASO, QUE PROPORCIONA MAYOR CONCENTRACION DE QUEMADO EN LA PARTE INFERIOR DEL HORNO, Y GRACIASA ESAS TEMPERATURAS SUPERIORES Y MEJOR ESTABILIDAD DE QUEMADO, PERO MENOS TRANSPORTES Y ARRASTRE DE IMPUREZAS DE PARTICULAS.THE INVENTION REFERS TO A SYSTEM AND DEVICE FOR IGNITION FUEL SUPPLIED WITHIN THE OVEN AS PARTICLES (1) SOLID OR FLUID, AND CONSISTING OF, FOR EXAMPLE, SPIRITED LIQUORS FROM THE PULP INDUSTRY AND ORGANIC CONTENT WHICH IS BURNED PARTIALLY AS INDUSTRIAL RESIDUAL COIL (2) ON THE FLOOR (3) OF THE OVEN, WITH GAS SPOUTS (4) CONTAINING OXYGEN, WHICH ARE USUALLY LOCATED IN HORIZONTAL ROWS AND PARTIALLY ABOVE THE OVEN IN RESIDUAL COIL SUSPENDED, AND AS VOLATILES, USING VERTICAL ROWS OF GAS SPRINKLERS (5) CONTAINING OXYGEN, WHICH ORIGINATE STRONG PERPENDICULAR FLOWS, OR, IN OTHER TERMS, PROVIDE A GOOD OXEN CONTACT. LOWER, SO REDUCING NOX EMISSIONS, BUT, ON THE OTHER HAND, VERY LOW VERTICAL GAS FLOWS, WHICH PROVIDES GREATER CONCENTRATION OF BURN IN THE BOTTOM OF THE OVEN, AND GR ACIASA THOSE HIGHER TEMPERATURES AND BETTER STABILITY OF BURN, BUT LESS TRANSPORTS AND DRAG OF IMPURITIES OF PARTICLES.
